The 1947 Frazer 6 Cyl. came to market in the immediate postwar years, when new American cars carried fresh styling and a strong emphasis on comfort, presence, and modern road manners for the time. That makes tire choice more than a simple maintenance item, because the right size helps preserve the car’s stance and period character. This Frazer uses a 6.50-15 bias-ply tire on a 15-inch rim, giving owners a traditional fitment path rather than a modern radial primary size. The main decision is choosing the right period-style tire within that size and confirming that the wheel setup still matches the car before putting it back on the road.
Which Tire Size Is Right for The 1947 Frazer 6 Cyl.
The 1947 Frazer 6 Cyl. uses one primary tire size: 6.50-15. That is a bias-ply fitment for a 15-inch rim, and it carries across the covered Base sub-model, so the focus is less about sorting between multiple factory sizes and more about selecting the right tire style for the car’s appearance, restoration direction, and road use.
A 6.50-15 size uses the vintage numeric bias-ply system, where the 6.50 designates a nominal section width of about 6.5 inches and the 15 identifies the rim diameter in inches. On a 1947 Frazer 6 Cyl., that format keeps the car in its proper period-style construction rather than shifting it into a modern metric radial presentation. Numeric bias-ply sizing is familiar on many postwar American cars and is part of the vehicle’s traditional visual character. For a restoration-minded owner, this size is the starting point for maintaining the Frazer’s intended look and wheel compatibility.
Tire fitment is straightforward for the covered 1947 Frazer 6 Cyl. sub-models. The Base model uses the same primary size, so the main task is confirming that the car still has the correct 15-inch wheel setup and a period-appropriate tire approach.

Frequently Asked Questions
Common questions for the 1947 Frazer 6 Cyl. usually come down to the 6.50-15 tire size, 15-inch rim fitment, period-style bias-ply selection, and the checks worth making before regular road use or restoration driving.
Tire Size & Fitment
What tire size fits a 1947 Frazer 6 Cyl.?
The 1947 Frazer 6 Cyl. uses a 6.50-15 tire. This is a vintage numeric bias-ply size and it is the primary fitment for the covered vehicle configuration, including the Base sub-model.
That means the first step is confirming that the car still has its 15-inch wheels and has not been changed to another wheel diameter over the years. On an older collector car, wheels, suspension, and even body clearance can change during restoration or modification, so the correct tire size should always be matched to the car’s actual setup.
What size rim does a 1947 Frazer 6 Cyl. use?
The primary tire fitment for the 1947 Frazer 6 Cyl. is built around a 15-inch rim. That rim diameter corresponds with the 6.50-15 tire size used on this vehicle.
Rim diameter is only part of the fitment picture, so it is worth checking the wheel itself before mounting new tires. A collector car may have replacement wheels that still measure 15 inches but differ in width or profile, and those changes can influence how a vintage bias-ply tire sits and clears the car.
Does the 1947 Frazer 6 Cyl. Base use the same tire size?
Yes. The covered 1947 Frazer 6 Cyl. Base uses the same 6.50-15 bias-ply tire size as the main model fitment. There is no separate primary size change within the sub-model coverage here.
That simplifies tire research because the buyer does not need to sort among several original fitment sizes for different trims. Even so, it remains smart to verify the actual wheels on the car, especially if it has been stored, restored, or modified over time, since old vehicles often carry changes that do not appear obvious at first glance.
Choosing the Right Tire
What should I consider when choosing a 6.50-15 tire for a 1947 Frazer 6 Cyl.?
Start with the correct primary size and construction. A 1947 Frazer 6 Cyl. uses a 6.50-15 bias-ply tire, so the choice begins with staying in the proper vintage sizing system and selecting a tire that suits the car’s period-style presentation.
From there, think about how the car will actually be used. A restoration-focused Frazer may call for a traditional visual look, while a driver should also be evaluated for wheel condition, suspension health, and road-readiness. Checking the wheel diameter, overall tire condition expectations, and how closely the tire matches the car’s character will usually matter more than chasing modern-looking alternatives.
How do I choose between the available 6.50-15 tires for a 1947 Frazer 6 Cyl.?
The right choice depends on the role of the car. Since the 1947 Frazer 6 Cyl. uses one main size, comparison usually centers on the tire’s visual style, how traditional the construction feels for the vehicle, and whether the car is being finished for restoration display or regular collector driving.
It helps to compare the tire against the car’s current wheels and overall presentation rather than looking at size alone. A postwar Frazer benefits from a tire that does not look out of place on the body and wheel combination, and owners should also consider load needs, storage habits, and how often the car will be driven before settling on a final selection.
What rim-fitment details matter when choosing tires for a 1947 Frazer 6 Cyl.?
The key fitment point is that the 1947 Frazer 6 Cyl. uses a 15-inch rim with its 6.50-15 tire size. That establishes the wheel diameter requirement, but older vehicles still need a closer look at the actual wheels in service.
Wheel width, wheel condition, and any aftermarket changes can affect how a tire seats and how it clears suspension and bodywork. On a long-restored or newly acquired car, checking for bent rims, corrosion at the bead area, mismatched wheels, and evidence of previous modifications can prevent problems that a simple size match would not reveal.
Restoration & Appearance
Which tire should I choose for a period-style 1947 Frazer 6 Cyl.?
A period-style starting point for the 1947 Frazer 6 Cyl. is the 6.50-15 bias-ply size. That keeps the car in the vintage numeric sizing system associated with postwar American fitment and supports a traditional look that suits the Frazer’s era.
Appearance-focused buyers should also think about how the tire complements the car’s wheels, ride height, and restoration goals. If exact originality matters beyond general period style, the safest next step is to compare against marque references, historical photos, or restoration documentation for the specific car rather than assuming every tire sold in the size reflects a factory-delivered appearance.
Does correct tire fitment matter for a 1947 Frazer 6 Cyl. restoration?
Yes, correct tire fitment matters because tire size and construction influence both appearance and how the car sits on the road. On a 1947 Frazer 6 Cyl., the 6.50-15 bias-ply fitment helps preserve the visual balance expected from a late-1940s American sedan.
A tire that departs too far from the proper period-style format can change the car’s stance and reduce the authenticity of the finished presentation. Even on a driver-level restoration, it is worth checking the wheel setup, the tire’s visual character, and the overall proportion of the car so the finished result looks coherent rather than merely functional.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1947 Frazer 6 Cyl.?
Yes. Even though the 1947 Frazer 6 Cyl. uses a 6.50-15 tire as its primary fitment, later changes can alter what actually works on the car. Replacement wheels, suspension work, brake changes, and body repairs can all influence usable tire clearance and wheel compatibility.
A Frazer that has been lowered, fitted with non-original wheels, or repaired around the fender openings may need closer measurement before new tires go on. Looking at wheel diameter, wheel width, steering travel, and available space around the tire helps prevent rubbing or mismatched fitment on a car that no longer matches stock dimensions.
What should I inspect before driving a 1947 Frazer 6 Cyl. on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and the surrounding suspension and steering components. On a 1947 Frazer 6 Cyl., it is also wise to confirm that the new 6.50-15 tires are mounted on sound 15-inch rims in good condition.
Collector cars often sit for long periods, so the overall chassis deserves attention along with the tires. Check for uneven ride height, loose steering parts, brake drag, and any signs that the tires contact body or suspension pieces during turning. Tire pressure should also be verified before driving, especially after initial mounting and the first few miles of use.
How should 6.50-15 tires on a collector 1947 Frazer 6 Cyl. be maintained?
Regular inspection matters more than mileage alone on a collector Frazer. A 6.50-15 tire should be checked for cracking, flat spotting, cuts, bulges, tread wear, and slow air loss, particularly when the car spends much of its time parked or in storage.
Storage conditions make a real difference on vintage tires and vintage cars. Keeping the Frazer away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition, while routine pressure checks and occasional movement of the car can reduce stress from long stationary periods. Any sign of age-related deterioration deserves prompt professional evaluation before road use.
